IMPROVEMENT IN LOCOMOTIVE-LAM PS.

Specification forming part of Letters Patent No. 35,122, dated April 29, 1862.

To @ZZ whom, t may concern:

Be it known that I, IRVTN A. WILLIAMS, of Utica, in the county of Oneida and State of New York, have invented a new and Improved Locomotive-Lamp5 and I do hereby declare that the followingI is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a vertical central section of my invention, taken in the line it' Fig. 2; Fig. 2, a horizontal section of the same, taken in the line y y, Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to a new and improved locomotive-lamp for burning coal-oil.

The object of the invention is to obtain a lamp for the purpose specified which will admit of the flame being supplied with a requisite quantity of oxygen to support proper combustion, and at the same time prevent the flame from flickering under the motion of the locomotive and from other disturbing causes which tend to produce .an uneven supply of air to the flame.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a fountain or reservoir, which contains the oil, and B is a tube which leads from said fountain or reservoir to a hollow cylindrical wick-tube, C, of annular form in its transverse section, and which contains a tubular wick, D, as shown clearly in Fig. l.

The above parts are well known, have been used in various kinds of lamps, and therefore do not require a minute description.

E F are two perforated cylinders, which encompass the wick-tube C, a space, a, being allowed between the two cylinders, anda space,

I), allowed between the inner cylinder, F, and the wick-tube C, as shown clearly in Fig. l. The inner perforated cylinder, F, extends upward some distance above the outer perforated cylinder, E, and on the upper end of the cylinder E there is placed a cap, G, the lower part, c, of which is of cylindrical form and the upper part, d, of conical form, the conical part d encompassing the base of the flame e. Hthin the wick-tube C there are placed two perforated horizontal disks, H I,

to which there is attached, centrally, an upright rod, f, having a button, g, at its upper end. Aperforated disk, J, is also placed in the lower part of the wick-tube (l.

K is a chamber or hollow base, which is permanently attached to the lower end of the wick-tube C. This chamber or base K is of flaring form, and its upper part projects beyond the tube C and is perforated with holes 7i at suitable distances apart. The upper part of the chamber or base K is covered by a perforated cap, L, said cap covering the perfor-ations h in the upper part of the base K, and being suiiiciently large to admit of a space, fz, all around the upper part of the chamber or base, between it and the cap L, as shown in Fig. l. The lower end of the chamber or base K is provided with a screwstopper, M.

From the above description it will be seen that the flame e is supplied with air internally through the perforated cap L, holes 7i. in the chamber or base K, said air passing up through the perforated disk J, the interior of the wick-tube C, and through the perforated disks II I, as indicated by arrows l. The Haine is supplied externally with air, which passes through the perforated cylinders E F, and thence up into the cap or defiector G, the upper part, d, of the cap deflecting the upward current of air upon the base of the flame, as indicated by the arrows i'.

The two perforated cylinders E F, with the spaces c IJ, cause a uniform passage of air up within the cap or deiiector G. They serve as equalizers, while the perforated cap L-and holes 71 in the chamber or base K, together with the space i and the perforated disks J H I, perform the same functions for the internal current of air. In consequence, therefore, of both currents of air which supply the flame being uniform or steady in their iiow or passage to the flame, the latter will burn without iiickering or smoking and with a brilliant illuminating flame. The Cap or deflector G insures the external current of air being thrown or deliected properly on the base or lower part of the flame e.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The perforated cylinders E F, one. or

more7 in Combina-tion with the cap or deleotl or G and holloW Wick-tube C, arranged substantially as and for the purpose specified.

2. The perforated Cylinders E F, one or more, otp or defleotor G, perforated hollow base K, provided with the perforated Cap L, in combination With the hollow Cylindrical 1 Wick-tube Q, all. arranged for joint operation, substantially as and for the prpose herein Set forth.
